Y., minors to International Mntosccpe Corporation, Long Island City,

a corporation of New York Application August 7, 1942, Serial No. 454,0466 Claims. (cl. 95-8) This invention relates to framed photographicplates.

One object of the invention is the provision of a combined framedphotographic plate and tray formed at least mainly of cardboard andpaper and characterized in that the frame is impervious to deleteriousaction by the chemicals or liquids utilized in treating the photographicplate following the exposure thereof in prepar-v ing the photograph. Inthis connection, the invention is concerned primarily with the provisionof a combined framed photographic plate and tray for use in photographicmachines of the type disclosed in United States Letters Patent No.2,192,755 in which machine the framed photographic plate is exposed,developed and fixed and thereafter dispensed by automatic operationsperformed by themachine pursuant to the insertion of a coin therein.

Another object of the invention is to provide a framed photographicplate which can be made from cardboard or paper stock in parts which canbe easily produced and easily assembled and which satisfies thepractical requirements in respect to the utility of these framed platesin a machine of the above'indicated type and which also satisfies therequirements as to the durability and the attractive appearance of theframed photographic plates.

The above and other objects, features and advantages of the presentinvention will be more fully understood from the reference being had tothe accompanying illustrative drawing.

In the drawing: I s Fig. 1 is a perspectiveyiew of combined plioto-=graphic plate and tray embodying the present invention;

Fig. 2 is a perspective view of part of the frame, taken from the backthereof;

Fig. 3 is a perspective view of a backing member forming a part of theframe;-

Fig. 4 is a perspective view of the photographic plate s Fig. 5is asectional vlew on the line 5-5 of Fig.

Fig. 6 is a view of the back of the complete frame. Referring now moreparticularly tothe drawing, the framed photographic plate ID of thepresent invention comprises a frame l2 having mounted therein aphotographic plate l4. Said frame is formed of cardboard or paper stockand said photographic plate is preferably a sheet of sensitized paper.

following description,

Frame 12 comprises front and rear frame members It and it formed ofcardboard or of paper stock. Said frame members are laminated or unitedwith each other in face-to-face relation and secured together in saidrelation by an interposed layer of adhesive as indicated at 20. Thussaid frame is solid for the full thickness thereof around the frontandrear openings 22 and 24. The opening 22 in front frame member I6 issomewhat smaller than the opening 24 in rear frame member It, thusproviding the frame with a peripheral shoulder 26 spaced from the frontof the frame. The outer peripheral edges of said frame members are inalignment and said openings are in central registry. The photographicplate l4 fits in the opening 24 of frame member 18 so that a peripheralmarginal edge portion of said photographic plate abuts said shouldercompletely therearound. A backing member 28 is positioned in the frameback of said photographic plate in the opening 24 of the rear framemember is. Said backing memher is also formed of cardboard or paperstock and is preferably the piece which is removed from the sheet informing the opening 24 in frame member to. In order to facilitate theassembly of backing member 28 with the other parts of the frame, theinner peripheral edge 30 of frame member I8 is preferably slightlytapered toward the front of the frame and the peripheral edge 32 ofbacking member 28 is correspondingly tapered, the taper of said edgesbeing conveniently formed when the part which constitutes backing member28 is cut from the material in producing the opening inv frame memberl8. As backing member 28 is preferably of the same thickness as framemember ill, the outer surface of said backing member, when positioned inopening 24, is substantially flush with the rear surface 0 frame memberl8. Said backing member is held of paper which is of subtantially thesame area as the back of the frame. Said sheet 34 extends across theperipheral joint between frame member I 8 and backing member 28 "and isformed of water repellant or water proof paper so that the back of theframe is substantially water proof or water repellant throughout thearea thereof and especially at the joint between frame member ltjandbacking member 28.

Backing member 28 and sheet 34 constitute means for holding thephotographic plate l4 against the peripheral shoulder 28 completelytherearound, thus providing a liquid tight Joint between saidphotographic plate and the inner in position by a sheet 34 curing sheetit in position, the latter is prefer- "ably provided with a watersoluble adhesive coating. The water utilized for moistening the adhesivecoating of sheet It has preferably added thereto a drying retardingagent, such as slycerin, whereby to prevent or delay for a long time thecomplete drying of sheet 34. This has been found beneficial inpreventing buckling or warping of the frame due to the contraction ofsheet 34. A relatively small quantity of an agent to prevent totaldrying is used in the water for moistening sheet 34.

It will be understood that when the framed photographic plate is used inthe photographic machine referred to above, said plate is preferablyalso a tray in which is contained the various liquids applied to thephotographic plate during the operation of th machine following theexposure of the photographic plate. It will be noted, therefore, thatthe construction of the framed photographic plate as described above issuch that the latter also constitutes a tray, the peripheral side wallof which is formed by the inner edge 36 of front frame member I: and

the bottom of which is constituted by the photographic plate ll. Asseveral liquids are applied to the photographic plate in the tray and asit is desirable to remove said liquids quickly, it is advantageous,although not necessary, to form edge 36 so that it tapers somewhattoward the bottom of the tray, that is toward plate It, thus tofacilitate the fiow of the liquids from the tray when the latter istilted during the several operations of the machine as described in saidpatent.

An important feature of the present invention, in addition to the abovedescribed construction of the combined framed photographic plate andtray, resides in the provision of the tray with means for preventing theliquids or liquid chemicalsfrom impairing the frame. For this purpose,the inner peripheral edge 38, and the front surface 38 of the frontframe member, and the outer peripheral edges 40 and 42 of frame membersi6 and I8, respectively, are rendered substantially waterproof andimpervious to the action of such liquids, it being notedfurther in thisconnection that as described above the back of the framed photographicplate is protected by the waterproof or water repellent backing sheet34. For thus providing the framed photographic plate with thisimpervious property, said portions thereof are coated with a suitablevar nish, preferably a varnish having a tar base, although other typesof waterproofing varnishes,

' such as for example a China-wood-oil varnish or a glyptal resinvarnish may be used. Asthe front surface 38 of the frame is providedwith ornamentation usually printed thereon, the varnish is applied oversaid ornamentation. For applying a varnish to edges 38, W and 42, theframes constituted by frame members it and it aresprayed at said edgeswith the varnish. This is conveniently accomplished by forming a stackof frame; I! with the inner and outer peripheral edges of said frames inregistry and with the frames in the stack held tightly against eachother forming in effect a tube, the varnish being sprayed on the innerand outer surfaces of this tube.

While we have shown and described the preferred embodiment of ourinvention, it will be understood that the latter may be 1 embodiedotherwise than as herein shown or described. It will be understood alsothat in the claims when the term "cardboard" is used, it embraces,unless otherwise specified, paper stock as well as cardboard proper.Since as stated, the invention may be otherwise embodied and since inthe 11- lustrated embodiment certain changes in the details ofconstruction may be made, we do not wish to be limited to the specificconstruction herein shown or described except to the extent which may berequired by the scope of the appended claims.
